To Change/Install Sand Belts
(See Parts Diagram and Parts List on pages 8 and 9)
Place switch in “OFF” position, and unplug the sander before performing any of the steps below.
The Oscillating Sander has been shipped completely assembled with a 2” sand belt (#49) and regular core board
installed. Change sand belts as follows:
TO REMOVE SAND BELT
1. Grasp and hold sand belt (#49) on rotating axle (#46). Loosen nut (#51). If nut is too tight and rotating axle
spins inside sand belt, secure the rotating axle with a wrench and loosen nut.
2. Remove nut, big washer (#50), and sand belt. Unscrew rotating axle clockwise and remove core board (#36) -
also see instructions below describing how to remove core board.
3. Remove big washer (#50) and clean sawdust accumulation.
TO INSTALL SAND BELT
1. Replace big washer (#50). Fin side of washer should always be installed down. The ns help push sawdust
through the dust exhaust port opening, preventing buildup of sawdust. Sawdust buildup in this area may cause
the oscillating motion to stop. The big washer must be used with all sanding sleeves.
2. Select and install the desired rotating axle.
3. Install appropriate sand belt on the rotating axle. (Note: If sanding sleeve becomes difcult to install or remove,
apply talcum powder on the inside of the sand belt before installing on axle).
4. Install big washer (#50) and nut.
5. Grasp and hold sand belt and tighten nut. Do not overtighten.
Replacing Core Boards
The Oscillating Sander comes with two core boards. The core board with the circular opening is for sanding when the working
table (#34) is level. The core board with the oblong opening is to be used when the working table is set at an angle.
To Remove Core Boards
Push rmly from underneath the working table until core board is removed.
To Insert Core Boards
1. Align the notch in the core board with the spring dowel (#35) located on the inner rim of the core board insert area.
2. Push down rmly until the core board is fully inserted and ush with the surface of the working table.

Preparing For Operation
Note:
√ This sander is designed for use on plastic and wood surfaces only. Do not use this sander for sanding
metals. Sanding metals will cause sparks that will ignite wood and dust particles on sander, in the dust
collector, or in workshop.
√ It is recommended that this tool not be used for extended work on any berglass or abrasive materials.
It has been found that those materials are subject to accelerated wear and possible premature failure,
as the berglass chips and grindings are highly abrasive to bearings, brushes, commutator, etc. During
any sanding of these materials, it is important the tool be cleaned frequently by blowing with an air
jet.
√ Do not use sander without a sand belt. Doing so will damage the rotating axle.
√ Make sure nut on the top of the rotating axle is tightened securely - but not overtightened.
SAND BELT SELECTION
Selecting the correct size diameter, type of grit and sanding sleeve is an extremely important step in achieving a
high quality nish:
√ Aluminum oxide, silicon carbide, and other synthetic abrasives are best for power sanding.
√ Natural abrasives, such as int and garnet are too soft for use in power sanding.
Select and install the desired sand belt for the particular application. Sand belts from 3/4”- 2” can be used with this
sander. Choose one that is close in size to the material you are sanding.
GRIT SELECTION
The condition of the surface to be sanded will determine which grit will do the proper job. In general, coarse grit will
remove the most material. Finer grit will produce the best nish in all sanding operations. If the surface is rough,
start with a coarse grit and sand until the surface is uniform. Medium grit may then be used to remove scratches
left by the coarser grit and ner grit used for nishing of the surface. Always continue sanding with each grit until
the surface is uniform.
WARNING! Do not use water with this sander. It is for dry
sanding only. Wet sanding will damage the machine,
and may present a shock hazard. Use only in dry
locations.
REV 10c

Operation
Exercise caution! Never force the material into the sander. You will become familiar with the sander’s features from
practice and use. If possible, practice sanding with a scrap piece of wood.
ADJUSTING TABLE ANGLE
1. If working table is to be used at an angle, make sure to install the angle core board (with the oblong-shaped
opening) before sanding.
2. Loosen dial knob (#32) and adjust working table to the desired angle using the numbers on the rotating plate
(#31) as a guide.
3. Tighten dial knob securely so that the working table will not move during operation.
SANDING
1. Turn sander on.
2. Let the motor build to its full speed, then gradually feed material against sanding sleeve. Do not let the material
contact sanding sleeve before turning on sander and allowing it to develop full speed.
FEED DIRECTION
When sanding, the sanding sleeve rotates counterclockwise. Therefore, feed the material against the sanding
sleeve from right to left. When fed from right to left, the rotation of the sanding sleeve sands against the material.
If fed in the opposite direction, the rotation forces of the spinning sanding sleeve will tend to throw or bounce the
material away from the sanding sleeve. This could cause loss of control of the material.
DUST COLLECTION CAPABILITY
A standard 2-1/4” dust collect cover (#40) has been provided to make dustless sanding possible. The dust collection
port is located under the working top on the rear side of the sander. The pickup adapter end of a vacuum hose (not
included) will t inside the dust collect cover.
Even with a dust collection system, it is necessary to periodically clean sanding dust from the core board and big
washer areas. Sanding dust buildup in this area may cause the core board surface to rise above the working table
surface.
Maintenance
CLEANING: Regularly clean the work surface with dry brush or clean cloth. Clean sawdust accumulations from core
board, big washers and rotating axle after each use.
LUBRICATION: No lubrication is required. All of the bearings in this tool are lubricated with a sufcient amount of
high grade lubricant for the life of the machine under normal operating conditions.
POWER CORD: Inspect the power cord periodically, and if damaged, have it repaired by an authorized technician.
REPLACEMENT PARTS: When servicing, use only identical replacement parts. Use of any other parts will void the
warranty.
